Find LCM of 210,784,310,363,243 with Prime Factorization


2 210, 784, 310, 363, 243
3 105, 392, 155, 363, 243
5 35, 392, 155, 121, 81
7 7, 392, 31, 121, 81
1, 56, 31, 121, 81

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 7 x 1 x 56 x 31 x 121 x 81 = 3573052560

LCM Formula to Find Lowest Common Multiple of 210,784,310,363,243

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

210 x 784 x 310 x 363 x 243 = 4502046225600

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

310 : 1, 2, 5, 10, 31, 62, 155, 310

363 : 1, 3, 11, 33, 121, 363

243 : 1, 3, 9, 27, 81, 243

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,784,310,363,243, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

784:2x 2x 2x 2x 7x 7

310:2x 5x 31

363:3x 11x 11

243:3x 3x 3x 3x 3

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 5x 7 = 1260

Therefore, the value for common factors is 1260.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 4502046225600/(1x1260)

LCM = 4502046225600/1260

LCM = 3573052560

Thus, we can understand that the LCM of 210,784,310,363,243 is 3573052560.
